Fifty students reported for a class that had 35 student desk-chairs: 30 RH (Right Hand) and five LH (Left Hand). Fifteen RH students then volunteered to transfer to an honors section down the hall, thereby leaving everyone in the original class seated.

After class, six RH students and one LH student reported their chairs were broken and needed replacing. Later that afternoon the honors instructor called saying that eight of the transfer students were not eligible for the honors class and were, therefore, returning to the original class.

How many additional RH and LH desk-chairs did the original instructor need for his class?
